(2) Regarding the temperatures of the rechargeable
battery.
The temperatures for rechargeable batteries are as
shown in the table below, and batteries that have
become hot should be cooled for a while before
being recharged.

(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown
in Table 3.

NOTE
The charging time may vary according to
temperature and power source voltage.
4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger firmly and pull out the battery.
NOTE
After operation, pull out batteries from the charger
first, and then keep the batteries properly.
Regarding electric discharge in case of new batteries,
etc.
As the internal chemical substance of new batteries
and batteries that have not been used for an
extended period is not activated, the electric
discharge might be low when using them the first
and second time. This is a temporary phenomenon,
and normal time required for recharging will be
restored by recharging the batteries 2 – 3 times.

How to make the batteries perform longer.
(1) Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the
electric current, the battery may be damaged and
its life will become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a
while.
CAUTION
If the battery is charged while it is heated because
it has been left for a long time in a location subject
to direct sunlight or because the batetery has just
been used, the pilot lamp of the charger lights up
green. In such a case, first let the battery cool, then
start charging.
When the pilot lamp flickers in red (at 0.2-second
intervals), check for and take out any foreign objects
in the charger's battery installation hole. If there are
no foreign objects, it is probable that the battery
or charger is malfunctioning. Take it to your
authorized Service Center.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC14YF2/UC24YFA is taken out, wait for a
minimum of 3 seconds before reinserting it to
continue charging. If the battery is reinserted within
3 seconds, the battery may not be properly charged.

PRIOR TO OPERATION

1. Setting up and checking the work environment
Check if the work environment is suitable by
following the precautions.

HOW TO USE

1. Confirm the cap position (see Fig. 5)
The tightening torque of this unit can be adjusted
according to the cap position, at which the cap is
set.
(1) When using this unit as a screwdriver, line up the
one of the numbers "1, 3, 5 ... 22" on the cap, or
the white dots, with the triangle mark on the outer
body.
(2) When using this unit as a drill, align the cap drill
mark " " with the triangle mark on the outer
body.
CAUTIONS
The cap cannot be set between the numerals "1,
3, 5 ... 22" or the white dots.
Do not use with the cap numeral between "22" and
the white line at the middle of the drill mark. Doing
so may cause damage. (See Fig. 6)
2. Tightening torque adjustment
(1) Tightening torque
Tightening torque should correspond in its intensity
to the screw diameter. When too strong torque is
